When adding and/or subtracting, your answer can only show as many decimal places as the measurement having the fewest number in the decimal places.
Yes
add them or subtract them, as appropriate!
Adding decimal same as adding whole numbers
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
First you write the decimals one under the other, in such as way that the decimal points are aligned.
When adding or subtracting measurements, the number of significant figures in the result should match the measurement with the least number of decimal places.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

Yes
When multiplying or dividing numbers, the result should have the same number of significant figures as the factor with the fewest significant figures. When adding or subtracting numbers, the result should have the same number of decimal places as the number with the fewest decimal places.

Adding decimal same as adding whole numbers
Significant figures are used to receive a more accurate number. To obtain the number you you multiply or divide the quantities, leave as many significant figures in the answer as there are in the quantity with the least number or significant figures. If adding or subtracting quantities, leave the same number of decimal places in the answer as there are in the quantity with the least number of decimal places
